"De­extinction"， the idea that extinct (绝种的) animals can be brought back through cloning or genetic (基因的) engineering，has attracted the interest of a small group of scientists. The topic has made the cover of National Geographic Magazine. Supporters say they are doing it for moral reasons and because we "miss" the extinct animals. They blame human exploitation (such as trapping，hunting, habitat destruction ) of the extinct animals, but their plans, though they sound exciting, are exploitation in another form.
